The Cardy-Cartan modular invariant (1201.4267v2)
Published 20 Jan 2012 in hep-th and math.QA
Abstract: Using factorizable Hopf algebras, we construct modular invariant partition functions of charge conjugation, or Cardy, type as characters of coends in categories that share essential features with the ones appearing in logarithmic CFT. The coefficients of such a partition function are given by the Cartan matrix of the theory.
